TROLLEY-WIRE AN 0 TROLLEY-WH EEL.

SPECIFICATION forming part of Letters Patent No. 567,186, datedSeptember 8, 1896. Application filled May 8,1396. seraino. 590,672. (Nomodel.)

To all whom it may concern:

Be it known that I, PATRICK CAssIDY, a citizen of the United States,residing at WVorcester, in the county of WVorcester and State ofMassachusetts, have invented a new and useful Improvement inTrolley-Wires and Trolley-\Vheels Therefor, of which the following is aspecification.

The aim of my invention is to provide a trolley-wire which may be easilyand firmly secured in position and which will present a large surface ofcontact to the trolley-wheels, and to provide a trolley-wheel ofpeculiar construction to accurately engage with said trolley-wire and torun centrally and easily in contact therewith. To these ends I form mytrolley-wire with a bead or projection, preferably substantiallycircular in cross-section, for engagement with the clips or hangers andwith a body portion or section, which is tapering or substantiallyV-shaped, for engagement with the trolley-wheel. To support the wire, Ipreferably employ clips or hangers which will engage with the groovesbetween the bead and the body portion of the wire. The trolley-Wheelwhich I preferably employ has a V-shaped groove corresponding with theV-shaped or tapered body portion of the wire, and in practice Ipreferably 'provide the trolley-wheel with a small clearance or wearinggroove, so that the trolley wheel and wire will wear evenly and a largesurface of contact be preserved. I The tapering or V- shaped bodyportion of the trolley-wire will present a large surface of contact tothe trolley-wheel, and the corresponding groove in the trolley-wheelwill keep the wheel centrally and nicely in contact with the wire, sothat the wheel will run very evenly and smoothly. 7

Referring to the drawings and in detail, Figure 1 shows the manner inwhich the trolley-wire is preferably supported and the form of wheelwhich is preferably used, and Fig. 2 is a perspective view of the wire.

Referring to the drawings and in detail, 10 10 designate the usual staysor crosswires. Carried by the cross-wires 10 are the hangers or clips 12for supporting the trolley-wire 11. The trolley-wire 11 is provided witha small bead or rib 13 for engagement with the hangers or clips 12. Thebead or rib 13 is preferably substantially circular in cross-section.The body portion 14 of the wire is made taperin g or substantiallyV-shaped in cross-secbetween the bead or rib l3 and the body por-- tionof the Wire. The trolley-wheel 15 is provided with a V-shaped ortapering groove, corresponding with the body portion 14 of thetrolley-wire 11. By means of this construction it will be seen that thesides 16 and 17 of the wheel 15 will have a large area of contact withthe trolley-wire. In practice I preferably form a slight Wearing grooveor depression 18 in the bottom of the V-shaped groove in thetrolley-wheel 15. By means of this construction the trolley wheel, andwire will wear down evenly and a large surface of contact will bepreserved. The tapered or body portion of the wire is preferably formedsubstantially at an angle of sixty degrees.

IVhile my construction is particularly adapted for overhead work, it maybe used in other locations, and changes and modifications may be made bya skilled mechanic without departing from the scope of my in ventionasexpressed in the claims. Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. As an article of manufacture, a trolleywire comprising asubstantially cylindrical rib or bead, and a tapering, substantially V-shaped body portion for engaging the trolleywheel, the rib and bodyportions of the wire being separated by substantially V-shaped groovesarranged to engage supporting clips or fasteners, substantially asdescribed.

2. The combination of a trolley-wire comprising a cylindrical bead, anda tapering or substantially V-shaped body portion for engaging thet-rolley-wheel, the rib and body portion of the wire being separated bysubstantially V-shaped grooves, and supporting clips or fasteners havingflexible arms arranged to be forced into engagement with said grooves,substantially as described.

3. The combination of a trolley-wire having a cylindrical rib, asubstantially V-shaped body portion, longitudinal substantially V shapedgrooves between the body portion and rib, supporting clips or hangershavin g flexi- In testimony whereof Ihave hereunto set ble arms arrangedto be foreed into engagemy hand in the presence of two subscribing mentwith said grooves, and a trolley-Wheel Witnesses. having a V-shapedgroove for engaging the PATRICK OASSIDY. body portion of thetrolley-Wire, and a Wear- Vitnesses: ing or clearance groove,substantially as de- PHILIP W.
